| Abstract |
|
After investigating the analytic model to predict penetration depth, we propose an analytical model which can be used in estimating the normal penetration characteristics of small projectiles, when they are impacted to the concrete targets with ordnance velocities. The major parameters of this model are nose factor of penetrator, compressive strength and density of targets, and impact velocity. We can predict accelerations, velocities, displacements of projectiles and applied forces by this proposed model. Estimated penetration depths were shown 5% error. We also verified the usefulness of the new method with laboratory impact test data. |
